1.	Sumitra has ₹ 34 in 50-paise and 25-paise coins. If the number of 25-paise coins is twice the number of 50-paise coins, how many coins of each kind does she have?
Answer» From the question,Sumitra has ₹34 = 3400 paise Let 50 paise coins be x And 25 paise coins be 2x Then, = 50x + 25 (2x) = 3400 = 50x + 50x = 3400 = 100x = 3400 Multiplying both side by (1/100). = 100x × (1/100) = (3400) × (1/100) = x = 34 ∴The number of 50 paise coins is 34 The number of 25 paise coins is 2x = 2 × 34 = 68

From the question,Sumitra has ₹34 = 3400 paise

Let 50 paise coins be x

And 25 paise coins be 2x

Then,

= 50x + 25 (2x) = 3400

= 50x + 50x = 3400

= 100x = 3400

Multiplying both side by (1/100).

= 100x × (1/100) = (3400) × (1/100)

= x = 34

∴The number of 50 paise coins is 34

The number of 25 paise coins is 2x = 2 × 34 = 68
